The eyes have a lot of different parts to it. The major ones are the cornea, pupil, sclera, the eyelash, lens, choroid and retina. The cornea have no blood vessels. The lens is held in place by suspensry ligaments which connects to ciliary process and ciliary muscle both are called the ciliary body. The sclera is fibrous tunic, which is highly vascular. The choroid is the pigmented tunic which is also highly vascular and the retina which is the visual tunic that is not vascular at all. Parasympathetic nerve impulses, circular muscles relax, radial muscles contract, the pupil dilates, and more light enters eye.
The eye has a lot to do with my everyday life. I have the worst eyes ever. Don't know how or why, maybe i sat in front of the TV to close i don't know. I am near cited, therefor i have to where contacts all the time, if i take them out i cant see 3 ft. in front of me. I don't know why exactly people lose there eyesight. i wish i hadn't, because contacts and glasses are a pain. But you gotta deal with whatever life throws at you. I'm also not aloud to drive without contacts or glasses, if i get caught driving without them i can get a hefty fine or even lost my licence.
